Lateral sepals oblique, a little widened at the base. Petals obliquely rhombic-oblanceolate, obtuse, glabrous, a little shorter than and adhering to the median sepal. Lip as long as the petals, oblong-cucullate, in front widened into a distinctly broader, subreniform, obtuse lobe, spur subquadrate, bifid almost up to the middle, 0.2 cm long. Column short, in front below the stigma provided with a double keel or lamella, glabrous, rostellum large. Anther ovate-oblong, cucullate, acuminate.
